Alkalol

Alkalol is a commercially available solution which can be used as an oral rinse or nasal irrigant. It is made by The Alkalol Company (Taunton, MA) and can be ordered by your pharmacist. It is fairly inexpensive (about $3.50 per pint, on average.) The active ingredients are salt (sodium chloride), alum (an astringent), and baking soda (sodium bicarbonate.) Alkalol also contains a number of natural extracts such as menthol and eucalyptol which, as far as I can tell, are present primarily for flavor.

The label says that Alkalol can be used at half or full strength, but I recommend that it be used at full strength. It can be safely used as a nasal irrigant or oral rinse.
